R&D&iActive Safety

To prevent accidents: this is the objective of active safety devices installed in automobiles.
We are vastly experienced in the definition of automobile components within this field. In order to do so, we use the most advanced software and rely on our test labs.

Components

The components for which we mainly develop solutions are the following::

  • Suspension systems (suspension arms, rebound stops, dust seals, etc.),
  • Steering systems (steering columns, link rods, knuckles, etc.), and
  • Brake systems (brake discs, brake pads, brake pistons, etc.).

 

During development we take the following into account:

  • The materials of which the components are going to be made,
  • Their manufacturing and assembly processes,
  • Their operating conditions once they are part of an automobile.
 

 

Mechanical and thermal analyses

By means of calculation tools, we reproduce the specifications contained in the functional requirements of components so as to analyse the evolution with time of, and the maximum values reached by, the variables:
  • Mechanical stress
  • Elastic and plastic deformations.
  • Temperatures.

 

These calculations may be performed in an uncoupled (mechanical and thermal phenomena independently) or a coupled (mechanical and thermal phenomena simultaneously) manner.

Durability/Fatigue

When components experience cyclic loads over long stretches of time, they may fail due to fatigue regardless of whether the mechanical stresses are significantly lower than the limits of the materials.
 
We are capable of determining the service life of components from:
  • The load cycles to which they are subjected during operation, and
  • A proper fatigue characterisation of the materials that are used to make them.
 

 

Vehicle dynamics

Vehicle dynamics allows to analyse the behaviour of a vehicle under different configurations (mass changes, suspension adjustment, use of electronic control, and so on) in different routes.

Nowadays we can perform these analyses in a virtual manner by using software tools specifically developed for this purpose (MSC Adams/Car, CarSim, etc.).

Vehicle response

Vehicle dynamics software enables us to analyse, for different driving conditions, the response of the vehicle with regard to:

  • Vehicle stability versus loss of control.
  • Evaluation of vehicle movements:
    • Sway/pitch
    • Yaw
 

 

This type of analysis also helps us to determine the mechanical stresses which automobile components experience according to the configuration of automobile systems as well as to the routes proposed (acceleration, braking, curve steering, driving through dips in the road, etc.).

Control developments

ABS, ESP, TCS and other types of active control systems are essential in current vehicles.

Co-simulation between MSC, ADAMS/Car and Matlab/Simulink makes it possible to specifically develop, tune and physically build the controllers to be installed in a vehicle.

They can be installed in both conventional internal combustion vehicles and electric vehicles with wheel hub motors.
